High CRI video lights for macro work

30 January 2016 - 03:25 PM

I'm looking into getting some high CRI lamps first and foremost for macro work.


I'm tempted by the FIX NEO 2200 pro lights http://www.fixneo.co...premium-2200-dx .

These are rated for 2200 lumens and a cri of 95 with a color temperature of 4000 kelvin.


But I fear they might not give enough light for macro video work?


What are the other high cri options?


I know of the Keldan Video 8m CRI but it's out of my price range.


The other option I know of are the I-Torch Venom c92 with CRI 92 and 4000 lumens. http://www.itorch.ca/venom-c92.html



Autofocus UW video with GH3 vs GH4 - focus breathing issues on GH4

02 November 2015 - 02:55 PM

First off all, I have done lots of UV videos with my GH3 and autofocus enabled and gotten great results. Hardly any annoying focus issues at all. Only minor stuff easily cut out during editing.


Switching to a new GH4 introduced a real pain in the ass autofocus action with continious focus breathing - almost cycling in and out of focus every couple of seconds.


Could this be a settings issue? The GH3 was so fine. Now my latest GH4 shoots look like a disaster.


My main lens is the Panasonic 7-14 mm.


Thanks for any advice.
